AUXILIARY GAUGES (if so
equipped)
1. Automatic Transmission fluid tempera-ture gauge
2. Voltmeter
3. Engine oil pressure gauge
4. Engine oil temperature gauge
Automatic Transmission fluid
temperature gauge
This gauge indicates the temperature of
the automatic transmission fluid.
CAUTION
• This gauge is not designed to indi-
cate low automatic transmission
fluid level. Use the dipstick to check
the fluid level. For additional infor-
mation, see “Automatic Transmis-
sion Fluid (ATF)” (P. 8-13).
• If the gauge indicates automatic
transmission fluid temperature over
the normal range, stop the vehicle as
soon as safely possible. It is recom-
mended that you have the vehicle
checked by a NISSAN dealer. Contin-
ued operation of the vehicle may se-
riously damage the transmission.
Voltmeter
When the ignition switch is placed in the ON
position, the voltmeter indicates the bat-
tery voltage. When the engine is running, it
indicates the generator voltage.
While cranking the engine, the volts drop
below the normal range. If the range is not
within the normal range (11 – 15 volts) while
the engine is running, it may indicate that
the charging system is not functioning
properly. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
Engine oil pressure gauge
The gauge indicates the engine lubrication
system oil pressure while the engine is run-
ning. The bar should be in the middle of the
gauge when the engine is running.
CAUTION
• This gauge is not designed to indi-
cate low engine oil level. Use the dip-
stick to check the oil level. For addi-
tional information, see “Engine oil”
(P. 8-8).
• If the gauge needle does not move
with the proper amount of engine oil,
it is recommended that you have the
vehicle checked by a NISSAN dealer.
Continued vehicle operation in such
a condition could cause serious dam-
age to the engine.
Engine oil temperature gauge
This gauge measures the temperature of
the engine oil.

CHECKING LIGHTS
With all doors closed, apply the parking
brake, fasten the seat belts and place the
ignition switch in the ON position without
starting the engine. The following lights (if
so equipped) will come on:
,or,,,or
The following lights (if so equipped) will
come on briefly and then go off:
,,,,,,,, ATP ,
If any light does not come on or operate in
a way other than described, it may indicate
a burned-out bulb and/or a system mal-
function. Have the system checked. It is
recommended that you visit a NISSAN
dealer for this service.
Some indicators and warnings are also dis-
played on the vehicle information display
between the speedometer and tachom-
eter. For additional information, see “Ve-
hicle information display” (P. 2-22).
WARNING/INDICATOR LIGHTS (red)
For additional information, see “Vehicle in-
formation display” (P. 2-22).
Automatic Transmission
Park warning light
(
model)
WARNING
• If the ATP light is on, this indicates
that the automatic transmission P
(Park) position will not function and
the transfer case is in N (Neutral).
• When parking, always make sure that
the 4WD shif t indicator light illumi-
nates and the parking brake is set.
Failure to engage the transfer posi-
tion in 2WD, 4H or 4LO could result in
the vehicle moving unexpectedly, re-
sulting in serious personal injury or
property damage.
• Shif t the 4WD switch into the 2WD, 4H
or 4LO position again to turn off the
ATP warning light when the shif t le-
ver is in the P (Park) position and the
ATP warning light is on. (Before shif t-
ing the 4WD switch into the 4LO posi-
tion, move the shif t lever into the N
(Neutral) position once, shif t the shif t
lever into P (Park) again and make
sure the ATP warning light is off.) If the 4WD mode indicator is off or the ATP
warning light is on, this indicates that the
automatic transmission P (Park) position
will not function and could result in the ve-
hicle moving unexpectedly, causing seri-
ous personal injury or property damage.
Always set the parking brake. For additional
information, see “Using 4–Wheel Drive
(4WD) (P. 5-109).
This light indicates that the automatic
transmission parking function is not en-
gaged. If the transfer control is not secured
in any drive position while the shif t lever is
in the P (Park) position, the transmission will
disengage and the drive wheels will not
lock.
orBrake warning
light
This light functions for both the parking
brake and the foot brake systems.
Parking brake indicator
When the ignition switch is placed in the ON
position, the light comes on when the park-
ing brake is applied.
Instruments and controls2-13

Low brake fluid warning light
When the ignition switch is placed in the ON
position, the light warns of a low brake fluid
level. If the light comes on while the engine
is running with the parking brake not ap-
plied, stop the vehicle and perform the
following:
1. Check the brake fluid level. Add brakefluid as necessary. For additional infor-
mation, see “Brake fluid” (P. 8-14).
2. If the brake fluid level is correct, have the warning system checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
WARNING
• Your brake system may not be work-
ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for re-
pairs. Otherwise, have your vehicle
towed because driving it could be
dangerous. •
Pressing the brake pedal with the en-
gine stopped and/or a low brake
fluid level may increase your stop-
ping distance and braking will re-
quire greater pedal effort as well as
pedal travel.
• If the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked. It is
recommended that you visit a
NISSAN dealer for this service.
Charge warning light
If this light comes on while the engine is
running, it may indicate the charging sys-
tem is not functioning properly. Turn the
engine off and check the generator belt. If
the belt is loose, broken, or missing or if the
light remains on, have the system checked.
It is recommended that you visit a NISSAN
dealer for this service.
CAUTION
• Do not ground electrical accessories
directly to the battery terminal. Do-
ing so will bypass the variable volt-
age control system and the vehicle
battery may not charge completely.
For additional information, see “Vari-
able voltage control system” (P. 8-18).
• Do not continue driving if the genera-
tor belt is loose, broken or missing.
Electric shif t control system
warning light
This light illuminates when a malfunction
occurs in the electric shif t control system.
When the master warning light illuminates,
the chime sounds and the following mes-
sage is displayed in the vehicle information
display: “When parked apply parking brake”.
When the ignition is placed in the OFF posi-
tion, the chime sounds continuously. En-
sure the parking brake is applied
Have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
